Water drainage spout, especially for hollow spaces in motor vehicle structures

Abstract

A water drainage spout, especially for hollow spaces in motor vehicle structures, which is so arranged that any water present in the hollow spaces is able to flow off by gravity when the vehicle stands still or drives, and in which the area serving the water drainage is surrounded on its side facing the atmosphere by a circumferential apron; the area serving the water drainage is constructed funnel-shaped and is closed off by a bottom adapted to be pushed through while water discharge openings are provided in the wall of the funnel distributed over the circumference thereof, which extend to this bottom.

We claim: 
     
       1. In a water discharge nozzle for hollow spaces of vehicle structures of the type having a means for preventing penetration of water from the exterior of the nozzle through a discharge opening of the nozzle which includes a unitary structure forming said nozzle and an apron means surrounding the nozzle and extending therebelow, the improvement wherein said unitary structure comprises a generally frusto-conical shaped depression having a peripheral wall and a closed circular vertex, a hollow cylindrically-shaped extension surrounding said depression and forming said apron, and discharge opening means formed in said depression above said vertex in a portion of the peripheral wall facing said extension and adjacent said vertex, and wherein said vertex is constructed so as to separate from said peripheral wall by pushing thereagainst. 
     
     
       2. A water drainage spout according to claim 1, characterized in that said water discharge opening means are arranged in wall portions of the defussion distributed over the circumference thereof. 
     
     
       3. A water drainage spout according to claim 2, characterized in that the spout is for hollow spaces in motor vehicle structures. 
     
     
       4. A water drainage spout according to claim 2, characterized in that lamellae means are provided within the area of the opening means which are each securely connected with the upper edge of the opening means. 
     
     
       5. A water drainage spout according to claim 4, characterized in that the ratio of inner width of the apron means to the diameter of the vertex is of the order of magnitude of about 6:1. 
     
     
       6. A water drainage spout according to claim 5, characterized in that the ratio of the height of the apron means to the diameter of the vertex is of the order of magnitude of about 4:1. 
     
     
       7. A water drainage spout according to claim 6, characterized in that the spout is for hollow spaces in motor vehicle structures. 
     
     
       8. A water drainage spout according to claim 1, characterized in that the ratio of the height of the apron means to the diameter of the bottom means is of the order of magnitude of about 4:1. 
     
     
       9. A water drainage spout according to claim 1, characterized in that the ratio of inner width of the apron means to the diameter of the vertex is of the order of magnitude of about 6:1. 
     
     
       10. A water drainage spout according to claim 9, characterized in that the ratio of the height of the apron means to the diameter of the vertex is of the order of magnitude of about 4:1. 
     
     
       11. A water drainage spout according to claim 1, characterized in that lamellae means are provided within the area of the opening means which are each securely connected with the upper edge of the opening means.
